Iphone 6 has trouble connecting to home Wi-Fi, but other devices connect to it flawlessly?

I noticed recently that I can't pick up a Wi-Fi signal from my router unless I'm standing beside it or in a close room. I have checked with other devices and this is not the case -- the Wi-Fi connects flawlessly and it is as fast as it always has been. It's just my phone! I have the latest iOS installed and have cleared networking data many times, but it still continues to not work. Any help is appreciated.

Added (1). I can connect to public Wi-Fi and other homes' networks, just not mine.

My kitten always lies on my iPhone?

My 3 month old kitten insists on laying on my iPhone. He'll headbutt it, purr as hes kneading on it, lick the screen, give love bites to the corner of the case, and lay on it to take naps. Is this normal? I don't really mind (sometimes it gets annoying when I'm trying to text) and he gives a little baby mew when you take it out from underneath him.

Anyone else have a kitty who loves technology? And if so, why? I get that computers are warm, but he only goes for my iPhone.

Connected my iPhone to my mac for the first time?

Will my photos be deleted from my mac?

I connected my iPhone to my mac for the first time and imported all of my photos. I then disconnected it and turned off photo stream on both devices. My iPhone storage is full so i want to delete my pictures but i still want them on my mac, so if i delete my photos from my iPhone, will the pictures still remain on my mac? And if i connect them again, will the new photos be imported and would the already deleted ones (on my iPhone) be lost?

Will my iPhone 6 record for over 8 hours straight?

I plan on moving from the upper Midwest to El Paso Texas. I will drive from my current residence to Denver Colorado which is a 8 hour drive. After spending the night, I will then take I-25 from Denver all the way down to El Paso. That's an additional 9 hours ish. I want to take a continues dash cam video of my travels. Will my iPhone 6 be able to handle that? If not what device would work?
